California Zika Mosquito Vectors

I have read the MS Zika mosquito vectors. The ability of the mosquito to transmit Zika virus is based on the combination of its competence and capacity.

Aegypti which is responsible for the current outbreak in the Americas.

California zika mosquito vectors. There are two culex mosquito types. Within the Flavivirus genus ZIKV is a mosquito-borne virus phylogenetically close to Japanese encephalitis JEV West Nile WNV dengue DENV and yellow fever YFV viruses 1. WHAT CALIFORNIANS NEED TO KNOW Zika virus is transmitted to people primarily through the bite of infected Aedes aegypti mosquitoes yellow fever mosquitoes or Aedes albopictus mosquitoes Asian tiger mosquitoes.

The mosquito-borne arbovirus Zika virus ZIKV Flavivirus Flaviviridae has caused an outbreak impressive by its magnitude and rapid spread. Primary Aedes species vector of Zika virus worldwide is A. MVCAC Mosquito and Vector Control Association of California The MVCAC aims to provide quality public information comprehensive mosquito and vector-borne disease surveillance training to high professional standards and effective legislative advocacy on behalf of California mosquito and vector control agencies.

Albopictus has been shown to be able to transmit Zika virus in Africaand in laboratory setting s. These results also indicate that Ae. Vector competence of Aedes aegypti Culex tarsalis and Culex quinquefasciatusfrom California for Zika virus.

First detected in Uganda in Africa in 1947 from where it spread to Asia in the 1960s it emerged in 2007 on the Yap Island in Micronesia and hit most islands in the Pacific region in 2013. The mosquito Aedes albopictus is a vector of dengue and Zika viruses. However since 2011 they have been detected in several California counties.

These mosquitoes are not native to California. During the recent Zika virus outbreak in 2016 enhanced surveillance for Aedes Aegypti and Aedes Albopictus mosquitoes across the United States allowed researchers to update previously presented county-level collection record maps for these mosquitoes Zika virus is primarily vectored by the Ae. This is very important for us–California and both nations–because we have Culex mosquitoes vectors of West Nile virus and so does Brazil said Leal whose UC Davis lab collaborates with the Ayres lab.

Additionally we work with other public agencies and institutions to educate the public on vectors the diseases they carry and prevention. Examples of common vectors include mosquitoes ticks mites and fleas. Insecticide-resistant mosquito populations have evolved in recent decades suggesting that new control strategies are needed.

Quinquefasciatus is not a competent laboratory vector of ZIKV. Hong Kong has a monsoon-influenced humid subtropical climate which favours the spread of mosquitoes. The northern and southern house mosquitoes.

These laboratory vector competence results support an emerging consensus that Cx. This MS nicely. About 80 of the mosquitoes fed through the Hemotek feeding system on ZIKV-containing sheep blood became infected but only 1323 developed dissemination infections.

The jury is still out by Walter S. Cassetti said the timeline for another outbreak relies on a number of factors including the density of Zika-naive patients and mosquito vectors in populated areas as well as the virus.

Competence for California mosquitoes and it supports results from many other studies which demonstrate that Cx. Vector competence of Aedes aegypti Culex tarsalis and Culex quinquefasciatus from California for Zika virus. Both types are vectors for West Nile virus but only the southern version has been shown to carry Zika virus.

Zika virus ZIKV belongs to the genus Flavivirus in the family Flaviviridae. Quinquefasciatus are not vectors of ZIKV. Part of our work is the surveillance monitoring and control of vectors that carry diseases such as West Nile virus and Lyme disease.

Aegypti mosquitoes exhibited infection rates of 8590 and transmission rates of 53 80 at 14 dpf. We Have a Mission. Of course these studies were done in the lab not the field and this is the beginning of the research.

A California City Is Fending Off Zika by Releasing 40000 Mosquitoes Every Week As disease-carrying mosquitoes continue their march across the United States communities are experimenting with new. Leal Department of Molecular and Cellular Biology University of California-Davis Davis USA. By contrast 60 of the mosquitoes fed blood-containing Chikungunya virus CHIKV became infected and 80 disseminated.

Aegypti from California are efficient laboratory vectors of ancestral and contemporary Asian lineage ZIKV.
